Wrong. Wings have structural limits IOW there is a limit to the air
pressure a wing can deal with. If you exceed a certain air speed in
descent a plane can go into an irrecoverable verticle dive or death
spin and in some cases the wings will simply snap off.

FFS . The VNE is NOT a stall.
In fact it is the direct opposite
You are demonstrating your complete ignorance of aeronautics
And WTF is a 'death spin ????

and how would you enter a spin from high speed.
Hey, maybe some-one mentioned a high speed spiral dive and you wanted
to look stupid

Actually a high speed stall has the same basic cause as any other stall i.e
the angle of attack of the wing to the airflow being too severe. A high
speed stall is caused when pulling out of a dive at highspeed such as in a
violent descent where doing so creates more than 1g of stress on the wings.
In which case it is possible for an aircraft to go into a spin. The problem
is related to gravity, speed and Newton's 1st law of motion :)

It is actually difficult to explain in words but makes perfect sense even in
some flight simulators. You have to remember of course the direction of the
airflow over the wings changes according to the angle of flight so even if
the angle of attack of the wing in relation to the ground is in effect below
the horizon because the plane is in descent. The actual airflow is coming in
the direction of travel so it is therefore possible for the wings angle of
attack in relation to the actual airflow to be too severe.

There is a small section about it in Wikipedia's entry on stall
http://en.wikipedia.org/wiki/Stall

A Death spin is a term I made up but should be self explanatory. Obviously
some stall and spin situations are irrecoverable particularly at low
altitude and where speed of descent exceeds the structural limitations of
the wings in which case attempting to correct the problem subjects the wings
to such extreme g-forces that they can simply snap off. Of course all these
things are fine to play with in a flight simulator, you wouldn't want it to
happen in real life since normally death is final. :(
